Abstract
An object of the present invention is to provide a golf ball which has an increased dry spin rate and wet spin rate on approach shots without sacrificing the processability into the cover. The present invention provides a golf ball cover material having shear loss moduli G1″ (Pa), G2″ (Pa), and G3″ (Pa) that satisfy following equations when measured using a dynamic viscoelasticity measuring apparatus at following conditions.log G1″≦7.09  (1)log G2″≧7.17  (2)log G3″≦7.14  (3)
